Answer:
D. All whole numbers less than or equal to 31
Step-by-step explanation:
The x value in this situation is the number of years after 1970 and until 2001.
This means that the domain will be the number of years after 1970 and until 2001.
Since the situation calculates the value of land in years after 1970, the domain will start at 0. Since it is until 2001, which is 31 years after 1970, the domain will go up to 31.
So, the domain will include all whole numbers less than or equal to 31.
The correct answer is D. All whole numbers less than or equal to 31

After 3 seconds it's been descending for 3 seconds at a rate of 2 feet per second. So it's gone down 6 feet, and now it's at a height of 67. So it started off at 73.
<span>Its height after x seconds is 73 - 2x. (73 to start off with, minus 2 feet per second that's passed.) </span>
<span>After 8 seconds it will be at a height of 73 - 2*8 = 73 - 16 = 57.</span>
B. less: because he wants to make money, if he produces less wheat ha can supply more corn which costs more.
Both of the Students are correct, where the units are the same in the beginning and at the end. If you divide 20 feet by 4, you get 5 feet or 60 inches. If you convert 20 feet to inches, you get 240 inches. When you divide 240 by 4, you get 60 inches. Therefore, they both are correct.
